Yamaha 2HP Gasoline Engine 操作手册说明书

Read these instructions and the instructions covering the operation of the engine before starting the engine. Do not operate the engine until you have put oil in the engine
crankcase. It is wise to check the oil level each time the gasoline tank is filled. If the pump is used only occasionally, check oil and gasoline before starting engine.
Do not run the pump dry. Always fill the pump body with water (or liquid to be pumped) before starting pump. It is not necessary to drain the pump body after use, unless there is a danger of e a regular grade of gasoline (unleaded and uncolored if available). Remove the engine cylinder head after 100 hours of operation and remove the carbon and lead deposits from the combustion chamber and top of the piston.Make certain that all hose and pipe connections are airtight. An air leak in the suction line may
prevent priming and will reduce the capacity of the pump.
Always place the pump as close to the liquid to be pumped as
possible. Keep the suction line short and with few bends. Keep the pump and
engine on a level foundation. A poor foundation and a heavy suction hose (made heavier when “primed’ full of liquid) could result in a pump “down the hole”. There are important instructions regarding
preparing the engine for long periods of idleness. (Read the engine instruction manual). Under these conditions, drain the pump completely, turn the engine over a few times and leave all plugs (filter and drain) out of the pump. Always try to store the unit in a heated and dry building.
When pumping dirty water or other liquids containing solids, always use a pump strainer on the end of the
suction line. There are no points on the pump which need lubrication. The shaft seal is self-lubricating, and designed to handle clean
or dirty liquids.

D ISASSEMBLY I NSTRUCTIONS:
1. Remove bolted clamp from shaft. Remove (4) bolts holding motor or Bearing Pedestal to the adapter plate.
2. Remove (6) nuts and lock washers holding adapter plate to housing. Using a screwdriver behind the side tabs, gently pry the adapter loose. Remove impeller, drive sleeve and seal assembly.
3. Remove two stainless steel flat head screws and remove wear plate. Replace the wear plate when there are surface grooves or excessive wear.
When reassembling, make sure there is no foreign material between the wear plate and the pump housing that would prevent the wear plate from lying flat.
4. Remove the seal and spring from the impeller and drive sleeve. Inspect the surface of the impeller sleeve. The surface can be cleaned with very fine sandpaper (#400) or if excessively worn or grooved, the impeller should be replaced. Remember, a worn impeller can cause an out of balance condition resulting in vibration and seal wear.
Always install a new seal assembly onto impeller before reassembling pump. It is very important not to scratch or mark the black carbon surface of the seal assembly.

5. Remove the white ceramic seal and rubber cup from the rear adapter. Clean the recess opening with sandpaper or wire brush.
Install the new seal half.
Very important to not scratch or mark the white ceramic seal surface. It is usually helpful to apply a small amount of lubrication to the rubber cap and then press the seal into position, using your two thumbs or arbor press to press in evenly. Make sure the seal is in position straight and true to prevent seal wobble.
position with impeller face against the banding material.
7. Install rear adapter using a new adapter gasket. Tighten (6) nuts.
8. Install pump to gas engine or bearing pedestal and tighten bolts.
Install bolted clamp and tighten bolts. The clamp bolts should be very tight. They should also be tightened equally so the space from side to side between clamps is equal for balance and to prevent vibration.
After all bolts are tight, grip the banding material and pull out.
After shim is removed the pump should turn freely.
